A new evidence-based standard for wind turbine maintenance is set to improve inspection accuracy and efficiency and help operators optimize end-of-life decisions, a lead author of the guidelines told New Energy Update.

Larger, higher efficiency turbines and the “clustering” of project resources are driving down offshore wind maintenance costs as they become increasingly important in project valuations, Tom Harries, Wind Energy Analyst at Bloomberg New Energy Finance (BNEF), said.

UK offshore battery projects set to be commissioned by Orsted and Statoil in early 2018 will generate valuable data on the revenue streams and right-sizing of energy storage installations, project directors told New Energy Update.
